[0028] A rectangular groove is formed inside the second rotating shaft 71 and is slidably matched with the limiting strip 77 .

[0029] Working principle: When using the mold clamping fixture for the machine tool, first, according to the width of the mold, the threaded rod 75 is rotated, and the threaded rod 75 moves longitudinally on the top of the outer cylinder 74. The threaded rod 75 drives the bottom connecting block 76 to rotate and move longitudinally at the same time. Since the cross-section of the limit bar 77 is rectangular and it slides in the rectangular groove of the second rotating shaft 71, the limit bar 77 drives the second rotating shaft 71 to rotate, and the second rotating shaft 71 drives the gear 72 to rotate, and the gear 72 drives the two sets of racks 73 to move toward each other, and the two sets of racks 73 drive the two sets of slides 5 to move toward each other on the outer wall of the slide rod 4, and the two ends of the mold are respectively placed on the top of the two sets of slides 5 for support, so as to adjust the position of the clamping mechanism according to the size of the mold;

[0030] Then, the air pump 67 is started to inflate, and the air pump 67 inflates the air into the air cylinder 6 through the second hose 68 and the first hose 66.

The connecting rod 63 drives the pressing block 64 to move downward, and the limiting rod and the connecting rod 63 are sealed by the sealing ring when sliding. When the piston 62 slides, the air cylinder 6 avoids the formation of negative pressure through the air holes on the bottom outer wall, until the pressing blocks 64 on the four groups of air cylinders 6 press on different positions of the top surface of the mold respectively, and the air pump 67 stops inflating. At this time, the mold is fixed. Otherwise, the air pump 67 is started to exhaust air. Under the action of the second spring 61, the pressing block 64 is reset to release the mold.

[0031] Finally, when it is necessary to process the other side of the mold, pull the latch 33, and the latch 33 slides in the rotating plate 32. At the same time, the latch 33 drives the fixed block 35 to squeeze the first spring 36, and the end of the latch 33 moves out of a group of slots 34 in the annular plate 31. At this time, the rotating plate 32 is rotated, and the rotating plate 32 drives the first rotating shaft 3 to rotate, and the first rotating shaft 3 drives the rectangular frame 2 to rotate in the inner groove until the latch 33 moves to correspond to the other slot 34. Then, release the latch 33, and the latch 33 is inserted into the other group of slots 34 under the action of the first spring 36, so that the first rotating shaft 3 can be positioned, so that the rectangular frame 2 is positioned after flipping, thereby facilitating the flipping of the fixed mold.
